It’s an interesting question. First you need a suitable tank for quarantining the coral then you need to decide for how long in a probably less optimal environment. I never used to quarantine my corals and only relied on dipping prior to placement. Then came the montipora eating nudibranchs! After losing all my montis in the display over several months, I then kept the tank monti free for about six months. Now I do quarantine any montis for several weeks in my soft coral tank before they go onto the main sps tank. They seem to tolerate being in with the softies at last for the short term.
I have not quarantined acros as I want them in the optimal environment from the get go and can’t afford to run a whole separate sps tank. I have had occasional acro flatworms but I get them with a turkey baster and a very helpful fairy wrasse which pretty much eliminates them.
Not all pests are equally destructive or difficult to eradicate. So it then would depend on what corals you are keeping and what hitchhikers you want to avoid
